Abstract
The utility model relates to a rolling mill speed sensor's protective structure, the rolling mill tip is provided with mounting panel (1), install rolling mill speed sensor (5) on the mounting panel, set up protective housing (4) on mounting panel (1), rolling mill speed sensor (5) are located inside protective housing (4), it has a plurality of rectangular shape point to examine inspection tour mouth (7) to open on protective housing (4), set up louvre (2) on the protective housing (4) cover body. The protective structure can effectively protect the rolling mill speed measuring system from running safely and stably, and meanwhile, the steel rolling production efficiency is improved, and a key effect is played for stable production.
Description
Technical Field
The utility model relates to a steel sheet is pricked technical field, concretely relates to rolling mill protector that tests speed.
Background
For a full continuous rolling production line, the full line comprises three areas of a primary rolling area, a middle rolling area and a middle finish rolling area, namely 23 rolling mills and 3 sets of flying shears. The rolling capacity is 200X 200, the blank is rolled into a section bar of flat steel or round steel series. Because the whole-line continuous rolling system needs to realize the whole-line linkage debugging of the rolling mills, each rolling mill realizes the automatic cascade debugging according to the roll diameter and the linear speed of the rolling mill. And the torque of the speed is timely adjusted according to the speed feedback of each rolling mill. Therefore, the requirements of products with different specifications on the control finishing degree of the rolling mill speed are higher, once the speed of one rolling mill fluctuates, the speed of the adjacent rolling mill is abnormal, the steel stacking and pulling condition of online rolled blanks is caused, the serious product quality problem is caused, and the online shutdown maintenance is required under the serious condition. Therefore, it is necessary to protect the speed measuring device of the rolling mill during the production process of steel rolling, and to ensure the improvement of reliable and stable operation of the speed measuring device of the rolling mill.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that provide a rolling mill speed sensor's protective structure to above-mentioned prior art, the installation is simple, structure safe and reliable, have good thermal diffusivity and the daily inspection of being convenient for.
The utility model provides a technical scheme that above-mentioned problem adopted does: the utility model provides a rolling mill speed sensor's protective structure, the rolling mill tip is provided with the mounting panel, rolling mill speed sensor installs on the mounting panel, set up the protection dustcoat on the mounting panel, rolling mill speed sensor is located inside the protection dustcoat, it has a plurality of rectangular shape point to examine the inspection mouth to open on the protection dustcoat, set up the louvre on the protection dustcoat cover body.
Preferably, the protective outer cover is provided with a flange, and the flange enables the protective outer cover to be fixed on the mounting plate through a connecting piece.
The speed measuring principle of the speed measuring device of the rolling mill is that the speed measuring device is connected to a motor of the rolling mill through a connecting shaft so as to detect the speed of the rolling mill.
Compared with the prior art, the utility model has the advantages of: through setting up the protection dustcoat, can effectively avoid rolling mill speed sensor to be disturbed by outside things, the protection dustcoat has heat dissipation, thermal-insulated effect simultaneously concurrently to convenient point is examined. The high-rotation-speed rotating shaft is prevented from being interfered by the outside, and the circuit and the bracket are prevented from being damaged.
Drawings
Fig. 1 is the embodiment of the utility model provides an in the embodiment of the rolling mill tip protector that tests the speed schematic diagram.
Fig. 2 is a side perspective view of the structure shown in fig. 1.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1 and 2, the rolling mill speed measuring device 5 in this embodiment is disposed on a mounting plate 1, the mounting plate 1 is located at the end of the rolling mill, the rolling mill speed measuring device 5 is connected to a motor of the rolling mill through a rotating shaft 6, the rotating shaft 6 interferes with the motor of the rolling mill through the mounting plate 1, and the rotating shaft rotates at a high speed with the motor during the operation of the rolling mill. The installation plate is characterized in that a protective outer cover 4 is arranged on the installation plate 1, the protective outer cover 4 is a semi-cylindrical hollow protective cover formed by processing and manufacturing iron plates, a plurality of strip-shaped point inspection ports 7 are formed in the cover body of the protective outer cover 4, small heat dissipation holes 2 are formed in the end face of the protective outer cover 4, the other end of the protective outer cover 4 is provided with an outward-turned flanging, and the flanging is fixed on the installation plate 1 through bolts 3. The rolling mill speed measuring device 5 is positioned inside the protective outer cover 4, and the rolling mill speed measuring device 5 and the rotating shaft 6 are prevented from being exposed through the protective outer cover 4.
In the above-mentioned structure, realized the protection to rolling mill speed sensor 5 through setting up protection dustcoat 4, have the function of heat dissipation and convenient point simultaneously concurrently, can in time realize that the heat is arranged outward, can avoid again that high temperature environment toasts rolling mill speed sensor 5's directness, makes things convenient for routine maintenance.
Although the preferred embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that modifications and variations of the present invention are possible to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
